Add category name to single advert page body class

  • Hi there,

    I have managed to add the advert category to the listings body class using the following code

    function add_category_name($classes = '') {
        $category_id = get_queried_object_id(); 
           $category = get_term( $category_id );
           $classes[] = 'category-'.$category->slug; 
      
        return $classes;
     }
     add_filter('body_class','add_category_name');

    But it doesn’t work on single ad pages – can anyone help?

    Hi,
    when you are viewing the Ad details page this code get_queried_object_id(); will return the ID of the Advert not category.

    You will need to check if the current page is a singular page and in this case, get the category slug differently

    
if(is_singular('advert')) {
  $terms = wp_get_post_terms( get_the_ID(), "advert_category" );
  foreach( $terms as $term ) {
    $classes[] = sprintf( "category-%s", $term->slug );
  }
} else {
  // your code here
}

    I did not test the code as I am not using my dev machine right now, but the general idea on how to get the slugs should be correct.

    Thanks Greg and sorry for the slow reply…

    Another quick question (sorry) how can you get only parent categories with that code?

    Hi,
    the wp_post_terms() function accepts a third param that allows filtering the results the same way WP_Query does https://developer.www.ads-software.com/reference/functions/wp_get_post_terms/, so in this case to show only the top categories you would need to change the line with wp_post_terms() function to

    
$terms = wp_get_post_terms( get_the_ID(), "advert_category", array( "parent" => 0 ) );
